Abstract
THE mass of the neutron has been calculated by Chadwick on the assumption that the neutrons of boron are emitted by the isotope 115B, according to the nuclear reaction. Using the exact masses of 115B, 42He and 147N and the maximum energy of the neutron excited by the rays of polonium, one may calculate for the neutron a mass 1.0068 (taking 16O = 16).1
